Abstract: PURPOSE: A multi-antenna wireless channel measurement device using multiple codes and an operation method thereof are provided to measure a wireless channel by transmitting codes for measuring various lengths based on the speed change of a mobile unit. CONSTITUTION: A timing unit(110) generates a code clock synchronized with other wireless channel measurement device and a synchronization signal. The timing unit determines code and measurement time for measurement according to the speed of an installed mobile unit in which a wireless channel measurement device is installed. A baseband unit(120) successively transmits codes for the measurement according to the synchronization signal. The baseband unit stores wireless channel measurement data by receiving the wireless channel measurement data in the measurement time. An RF(Radio Frequency) module(130) transmits the code for the measurement through a multi-antenna. The RF module receives the wireless channel measurement data.

Abstract: 신호의 재전송시에 기지국과 단말을 중계하는 협력 중계기가 개시된다. 또한 협력 중계기와 상호 협력하여 단말로부터 신호를 수신하는 기지국이 개시된다.
협력 중계기는 단말이 기지국 또는 서비스 중계기에 송신한 신호를 수신하고 복호하여 복호된 신호에 오류가 없는 경우 수신한 신호를 저장한다. 기지국은 단말이 송신한 신호를 복호할 때 오류가 발생하면 오류가 발생한 신호에 대한 재전송을 협력 중계기에 요청한다. 협력 중계기는 재전송을 요청 받으면 기지국이 요청한 신호를 기지국에 전송한다.
이로써, 기지국의 신호 재전송 요청시에 오류율을 낮출 수 있으므로, 자원 재사용 효율이 좋아지고, 간섭량은 낮아지며, 시간 지연에 민감한 서비스에의 적용이 용이하다.
